The worst I have seen are focussing rings which get a little loose and slip,
this has happened to my oldest Zuikos.

Don't know.

I have a feeling that exposure to excess heat for a long period might do it,
e.g. keep it in a car in the open for a week or two like we've just had
here. This probably stuffs the cement used in any of the cemented elements
and causes the lubricants to get runny and move around (diaphragm blades,
etc.) as well.
